VALVE-REMOVING APPARATUS.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed October 19,1904. Serial No. 229,099.

To all whom it may concern.-

Be it known that I, MARVIN A. NEELAND, of Youngstown, Mahoning county, Ohio, have invented a new and useful Valve-Re moving Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in Which Figure 1 is a side elevation showing my im proved apparatus in position beneath the exhaust-valve of a gas-engine. Fig. 2 is a side elevation of the car on a larger scale. Fig. 3 is a cross-section on the line III III of Fig. 4. Fig 4 is a sectional elevation showing the raising and lowering device. Fig. 5 is a sectional view of the carpit; and Fig. 6 is a plan view of the pits, showing a carriage.

My invention relates to apparatus for the removal and replacing of engine-valves, particularly the exhaust-valves of gasengines.

In gas-engines of large horse-power these exhaust-valves are heavy and difficult to re move and replace. The valve being ordinarily beneath the end portion of'the cylinder cannot be reached with an ordinary crane, and as the valve must be frequently removed for examination and replaced, it is desirable to provide some means for rapid and easy removal of the valve.

My invention provides such a device, which maybe moved underneath the valve and the valve lowered upon it to provide for examination.

It also provides for removal of the valve to the side of the engine, where it may be lifted by a crane and taken away for regrinding or replacing.

In the drawings, 2 represents the end portion of a gas-engine cylinder having an exhaust-valve casing 3 underneath it secured thereto by suitable bolts 4. Beneath the exhaust-valve I provide a pit which extends transversely to the engine-pit and laterally to one side of the engine. In this pit are provided tracks 5, upon which travel the wheels of a car having aframe 6 of any suitable form. Depending from this frame are guides 6, preferably formed of channels, as shown in Fig. 3, these being secured together at their lower ends by the cross-piece 7. Within the guides 6 move the side members 8 of a sliding frame having a top support 9 arranged to receive the valve and easing. A central screw-threaded stem 10 extends through the lower cross-piece 7 and supports the sliding frame, being attached to the cross-head 11,

secured near the bottom of the sliding frame. This screw-stem is engaged by an internallythreaded hand-wheel 12, supported in suitable bearings upon the lower cross-piece 7, so that by turning the hand-wheel the sliding frame may be raised and lowered. The side members 8 of the frame are guided by the webs of the channels 6, and also preferably by wooden guide-blocks inserted between their flanges and the flanges of the channel 6.

In Fig. 6 I show a plan view of the pit arrangement. In this view the two car-pits 13 are shown as extending atright angles to the main engine-pit across their ends, the tracks 5 extending through the car-pits, so that either car may be moved to one side of the engine to allow a crane to reach the valve casing and its contained parts. The pit being open at one side of the engine, the entire car can be lifted up and transferred to the other pit of the same engine or to similar pits of other engines, thus enabling a single car to be used for a series of pits.

In using the device the car is moved to a osition where the sliding frame registers with the exhaust-valve casing, the screw is actuated to force up the sliding frame, prefer ably far enough to take the weight of the valve and casing, and the bolts are then loosened and the sliding frame lowered. Repairing or regrinding may be ,done in this position, or, if found necessary to remove the parts, the car is moved sidewise on its track to a position at one side of the engine, thus making it accessible for an overhead crane, by which the casing or parts may be taken away to be reground, repaired, or replaced.

The advantages of my invention result from the rapidity and ease of removing and replacing the exhaust-valve. The car being underneath the valve and being movable at one side of the engine, the valve can not only be lowered, but can be brought outside the engine, so that it can be easily reached by a crane or other device.

The car may be mounted upon slides instead of wheels, and many other changes may be made in the form and arrangement of the car, the raising and lowering means, and the other parts without departing from my invention.

I claim 1. A support mounted in a space below the valve-casing underneath an engine-cylinder, and movable vertically and sidewise in said space; substantially as described.

2.. A vertically-movable support mounted in a space below the valve-casing underneath an engine-cylinder, and a sidewise-movable 'car on said support; substantially as described.

3. In an engine installation, a pit extending below the valve-casing underneath an engine-cylinder, said pit extending to one side of the engine, and mechanism arranged to lower the valve-seat within the pit and move it therein to one side of the engine; substantially as described.

4. In an engine installation having a valve casing underneath an engine-cylinder, a pit underneath the valve and extending to one side of the engine, a car movable upon a track within said pit, and a vertical adjustable support upon the car arranged to register with the valve-seat in one position of the car; substantially as described.

5. In an engine installation having a valvecasing underneath an engine-cylinder, a pit underneath the valve extending to one side of the engine, a car movable within said pit, a vertically-movable support on the car, and screw mechanism for raising and lowering the said support; substantially as described.

6. In an engine installation having a valvecasing underneath an engine-cylinder, a pit beneath the valve extending to one side of the engine, a car movable within the pit and having vertically-extending guides, a vertical-movable frame within the guides, and hand-controlled screw mechanism for raising and lowering the support; substantially as described.

7. A valve-removing device comprising a horizontally-moving car having a verticallymoving frame arranged to be brought into position beneath a valve-case; substantially as described.

8. A vertically-movable support capable of being brought into position under the underneath valve-casing of a cylinder, said sup port being also capable of lateral movement from beneath said casing; substantially as described.

9. A U-shaped horizontally-movable car having a vertically-movable support with a U-shaped top member arranged to be brought into position beneath a valve-casing of a cylinder; substantially as described.

In testimony whereof I have hereunto set my hand.
